(c) The Administrative Agent shall maintain accounts in which it shall record (i) the amount of each Loan made hereunder, the Type thereof and the Interest

44

Period applicable thereto, (ii) the amount of any principal or interest due and payable or to become due and payable from the Borrower to each Lender hereunder and (iii) the amount of any sum received by the Administrative Agent hereunder for the account of the Lenders and each Lender’s share thereof.

(d) The entries made in the accounts maintained pursuant to paragraph (b) or (c) of this Section shall be prim a facie evidence of the existence and amounts of the obligations recorded therein; provided that the failure of any Lender or the Administrative Agent to maintain such accounts or any error therein (including any failure to record the making or repayment of any Loan) shall not in any manner affect the obligation of the Borrower to repay the Loans in accordance with the terms of this Agreement.

(e) Any Lender may request that Loans made by it be evidenced by a promissory note. In such event, the Borrower shall prepare, execute and deliver to such Lender a promissory note payable to the order of such Lender (or, if requested by such Lender, to such Lender and its registered assigns) in substantially the form set forth in Exhibit D . Thereafter, the Loans evidenced by such promissory note and interest thereon shall at all times (including after assignment pursuant to Section 9.04) be represented by one or more promissory notes in such form payable to the order of the payee named therein (or, if such promissory note is a registered note, to such payee and its registered assigns).

SECTION 2.05. Prepayments. (a) The Borrower shall have the right at any time and from time to time to prepay any Borrowing in whole or in part without premium (but subject to Section 2.10).

(b) When the aggregate amount of Excess Proceeds exceeds $10,000,000, the Borrower shall within 15 days notify the Administrative Agent thereof and prepay the Loans in the amount of such Excess Proceeds without premium (but subject to Section 2.10) (as reduced by any portion thereof which has been rejected by Declining Lenders pursuant to clause (e) below and specified in a notice delivered by the Administrative Agent to the Borrower). To the extent there are any remaining Excess Proceeds following the completion of the prepayment required hereunder as a result of Lender elections not to accept such prepayment, the Borrower shall apply such Excess Proceeds to the repayment of other Indebtedness of the Borrower or any Restricted Subsidiary that is a Subsidiary of the Borrower, to the extent permitted or required under the terms thereof. Any other remaining Excess Proceeds may be applied to any use as determined by Level 3 which is not otherwise prohibited by this Agreement, and the amount of Excess Proceeds shall be reset to zero.

(c) Not fewer than 30 days prior to any payment or prepayment of any principal amount of the Loan Proceeds Note, the Borrower shall notify the Administrative Agent thereof and shall, on the date of such payment or prepayment, subject to paragraph (e) below, prepay the Loans at a price equal to the principal amount of the Loans without premium (but subject to Section 2.10); provided , however that (i) on the date of such payment or prepayment of the Loan Proceeds Note, the Administrative

45

Agent shall notify the Borrower of the required amount of such prepayment (as reduced by any portion thereof which has been rejected by Declining Lenders pursuant to clause (e) below) and (ii) the Borrower shall immediately prepay the Loans in such amount in accordance with clause (e) below.

(d) Upon the occurrence of a Change of Control Triggering Event, the Borrower shall within 30 days of such occurrence notify the Administrative Agent thereof and prepay the Loans not later than 30 Business Days following such notification; provided , however that (i) at the expiration of such 30 Business Day period, the Administrative Agent shall notify the Borrower of the required amount of such prepayment (as reduced by any portion thereof which has been rejected by Declining Lenders pursuant to clause (e) below) and the Borrower shall immediately prepay the Loans in such amount in accordance with clause (e) below and (ii) the Borrower shall also pay, on the date of such prepayment, to each Lender receiving such prepayment a fee equal to 1.00% of the principal amount of the Loans prepaid to such Lender.

(e) With respect to any proposed mandatory prepayment of the Loans pursuant to clause (b), (c) or (d) above, any Lender may, at its option, elect not to accept such prepayment (any Lender making such election being a “ Declining Lender ”) as follows: each Declining Lender shall give written notice thereof to the Administrative Agent not later than 10:00 a.m. New York City time on the date which is two Business Days prior to the date on which the Administrative Agent is required to notify the Borrower of the amount of the applicable prepayment pursuant to clause (b), (c) or (d) above. On the date of prepayment, an amount equal to that portion of the Loan then to be prepaid (less the amount thereof that would otherwise be payable to Declining Lenders) shall be paid to the Lenders that are not Declining Lenders in accordance with subsection (f) below. In the event that the Administrative Agent has not, with respect to any mandatory prepayment, received a notice from a Lender in accordance with this clause (e), such Lender shall be deemed to have waived its rights under this clause (e) to decline receipt thereof.

(f) The Borrower (or Level 3 on its behalf) shall notify the Administrative Agent by telephone (confirmed by telecopy) of any prepayment hereunder not later than 1:00 p.m., New York City time, two Business Days before the date of prepayment or such lesser period as may be acceptable to the Administrative Agent. Each such notice shall be irrevocable and shall specify the prepayment date, the principal amount to be prepaid and, in the case of a mandatory prepayment, a reasonably detailed calculation of the amount of such prepayment. Promptly following receipt of any such notice, the Administrative Agent shall advise the Lenders of the contents thereof. Prepayments shall be accompanied by accrued interest to the extent required by Section 2.07. If any prepayment pursuant to this Section is made by the Borrower other than on the last day of the Interest Period applicable to any prepaid Eurodollar Loans, the Borrower shall also pay to each Lender (other than any Declining Lender) on the date of such prepayment any amount owing to such Lender pursuant to Section 2.10.

46

SECTION 2.06. Fees. (a) Level 3 and the Borrower agree to pay to the Administrative Agent, for its own account, fees payable in the amounts and at the times separately agreed upon by the Borrower and the Administrative Agent.

SECTION 2.07. Interest. (a) The Loans comprising each ABR Borrowing shall bear interest at the Alternate Base Rate plus the Applicable Margin. The Loans comprising each Eurodollar Borrowing shall bear interest at the LIBO Rate for the Interest Period for such Borrowing plus the Applicable Margin.

(b) Notwithstanding the foregoing, if any principal of or interest on any Loan or any fee or other amount payable by the Borrower hereunder is not paid when due, whether at stated maturity, upon acceleration or otherwise, such overdue amount shall bear interest, after as well as before judgment, at a rate per annum equal to (i) in the case of overdue principal of any Loan, 2.00% per annum plus the rate otherwise applicable to such Loan as provided in paragraph (a) of this Section or (ii) in the case of any other amount, 2.00% per annum plus the rate that would at the time be applicable to an ABR Loan as provided in paragraph (a) of this Section.

(c) Accrued interest on the Loans shall be payable in arrears on each Interest Payment Date; provided that (i) interest accrued pursuant to paragraph (b) of this Section shall be payable on demand and (ii) in the event of any repayment or prepayment of the Loans, accrued interest on the principal amount repaid or prepaid shall be payable on the date of such repayment or prepayment.

(d) All interest hereunder shall be computed on the basis of the actual number of days elapsed in a year of 365 days (or 366 days in a leap year), and in each case shall be payable for the actual number of days elapsed (including the first day but excluding the last day). The applicable LIBO Rate or Alternate Base Rate shall be determined by the Administrative Agent, and such determination shall be conclusive absent manifest error.

SECTION 2.08. Alternate Rate of Interest. If, prior to the commencement of any Interest Period for a Eurodollar Borrowing, the Administrative Agent determines (which determination shall be conclusive absent manifest error) that adequate and reasonable means do not exist for ascertaining the LIBO Rate for such Interest Period, then the Administrative Agent shall give notice thereof to Level 3 and the Lenders by telephone or telecopy as promptly as practicable thereafter, whereupon each Eurodollar Loan shall automatically, on the last day of the current Interest Period for such Eurodollar Loan, convert into an ABR Loan and the obligations of the Lenders to make Eurodollar Loans shall be suspended until the Administrative Agent notifies Level 3 and the Lenders that the circumstances giving rise to such notice no longer exist.

SECTION 2.09. Increased Costs. (a) If any Lender shall notify the Administrative Agent and Level 3 at any time that Eurocurrency Reserve Requirements are, or are scheduled to become, effective and that such Lender is or will be generally subject to such Eurocurrency Reserve Requirements and will, as a result, incur additional costs, then such Lender shall, for each day from the later of the date of such notice and

47

the date on which such Eurocurrency Reserve Requirements become effective, be entitled to additional interest on each Eurodollar Loan made by it at a rate per annum determined for such day (rounded upward to the nearest 100th of 1%) equal to the remainder obtained by subtracting (i) the LIBO Rate for such Eurodollar Loan from (ii) the rate obtained by dividing such LIBO Rate by a percentage equal to 100% minus the Eurocurrency Reserve Requirements then-applicable to such Lender. Such additional interest will be payable in arrears to the Administrative Agent, for the account of such Lender, on each Interest Payment Date relating to such Eurodollar Loan and on any other date when interest is required to be paid hereunder with respect to such Loan. Any Lender giving a notice under this paragraph (a) shall promptly withdraw such notice (by written notice of withdrawal given to the Administrative Agent and Level 3) in the event Eurocurrency Reserve Requirements cease to apply to it or the circumstances giving rise to such notice otherwise cease to exist.

(b) If any Change in Law shall:

(i) impose, modify or deem applicable any reserve, special deposit or similar requirement against assets of, deposits with or for the account of or credit extended by any Lender (except any Eurocurrency Reserve Requirement); or

(ii) impose on any Lender or the London interbank market any other condition affecting this Agreement or Eurodollar Loans of such Lender;

and the result of any of the foregoing shall be to increase the cost to such Lender of making or maintaining any Eurodollar Loan or to reduce the amount of any sum received by such Lender, then Level 3 and the Borrower will pay to such Lender such additional amount or amounts as will compensate such Lender for such additional costs incurred or reduction suffered. This Section shall not apply to any additional costs or reductions relating to Taxes, which are governed by Section 2.11.

(c) If any Lender determines that any Change in Law regarding capital requirements has or would have the effect of reducing the rate of return on such Lender’s capital or on the capital of such Lender’s holding company, if any, as a consequence of this Agreement or the Loans made by such Lender to a level below that which such Lender or such Lender’s holding company could have achieved but for such Change in Law (taking into consideration such Lender’s policies and the policies of such Lender’s holding company with respect to capital adequacy), then from time to time Level 3 and the Borrower will pay to such Lender such additional amount or amounts as will compensate such Lender or such Lender’s holding company for any such reduction suffered.

(d) A certificate of a Lender setting forth the amount or amounts necessary to compensate such Lender or its holding company, as the case may be, as specified in paragraph (b) or (c) of this Section shall be delivered to Level 3 and shall be conclusive absent manifest error. Level 3 and the Borrower, as the case may be, shall pay such Lender the amount shown as due on any such certificate within 10 days after receipt thereof.

48

(e) Failure or delay on the part of any Lender to demand compensation pursuant to this Section shall not constitute a waiver of such Lender’s right to demand such compensation; provided that Level 3 and the Borrower shall not be required to compensate a Lender pursuant to this Section for any increased costs or reductions incurred more than 180 days prior to the date that such Lender notifies Level 3 of the Change in Law giving rise to such increased costs or reductions and of such Lender’s intention to claim compensation therefor; provided further that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the 180-day period referred to above shall be extended to include the period of retroactive effect thereof.

(f) The provisions of Section 2.09(a) and (c) shall only be available to Lenders regulated by Federal banking authorities.

SECTION 2.10. Break Funding Payments. In the event of (a) any payment of any principal of any Eurodollar Loan other than on the last day of an Interest Period applicable thereto (including as a result of an Event of Default), (b) the failure to borrow or prepay any Eurodollar Loan on the date specified in any notice delivered pursuant hereto, or (c) the assignment of any Eurodollar Loan other than on the last day of the Interest Period applicable thereto as a result of a request by Level 3 pursuant to Section 2.13, then, in any such event, Level 3 and the Borrower, as applicable, shall compensate each Lender for the loss, cost and expense attributable to such event. In the case of a Eurodollar Loan, such loss, cost or expense to any Lender shall be deemed not to include any lost profit (including loss of Applicable Margin) and shall be deemed to include an amount determined by such Lender to be the excess, if any, of (i) the amount of interest that would have accrued on the principal amount of such Loan had such event not occurred at the LIBO Rate that is or would have been applicable to such Loan, for the period from the date of such event to the last day of the then current Interest Period therefor (or, in the case of a failure to borrow, convert or continue, for the period that would have been the Interest Period for such Loan), over (ii) the amount of interest which would accrue on such principal amount for such period at the interest rate which such Lender would bid were it to bid, at the commencement of such period, for dollar deposits of a comparable amount and period from other banks in the eurodollar market. A certificate of any Lender setting forth any amount or amounts that such Lender is entitled to receive pursuant to this Section shall be delivered to Level 3 and shall be conclusive absent manifest error. Level 3 or the Borrower, as applicable, shall pay such Lender the amount shown as due on any such certificate within 10 days after receipt thereof.

SECTION 2.11. Taxes. (a) Any and all payments by or on account of the obligations of the Borrower hereunder or under any other Loan Document shall be made free and clear of and without deduction for any Indemnified Taxes or Other Taxes; provided that if the Borrower shall be required to deduct any Indemnified Taxes or Other Taxes from such payments, then (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section) the Administrative Agent or Lender (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall make such deductions and (iii) the Borrower shall pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law.

49

(b) In addition, the Borrower shall pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law.

(c) Level 3 and the Borrower shall indemnify the Administrative Agent and each Lender, within 10 days after written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes paid by the Administrative Agent or such Lender, as the case may be, on or with respect to any payment by or on account of any obligation of the Borrower hereunder or under any other Loan Document (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section) and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to Level 3 or the Borrower by a Lender, or by the Administrative Agent on its own behalf or on behalf of a Lender, shall be conclusive absent manifest error.

(d) As soon as practicable after any payment of Indemnified Taxes or Other Taxes by the Borrower to a Governmental Authority, the Borrower shall deliver to the Administrative Agent reasonably satisfactory evidence of such payment and the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment; provided however in no case shall the Borrower be required to deliver documentation not normally issued by such Governmental Authority.

(e) Any Foreign Lender that is entitled to an exemption from or reduction of withholding tax under the law of the jurisdiction in which the Borrower is located, or any treaty to which such jurisdiction is a party, with respect to payments under this Agreement shall deliver to the Borrower and Level 3 (with a copy to the Administrative Agent), at the time or times prescribed by applicable law, such properly completed and executed documentation prescribed by applicable law or reasonably requested by the Borrower and Level 3 as will permit such payments to be made without withholding or at a reduced rate.

SECTION 2.12. Payments Generally; Pro Rata Treatment; Sharing of Set-offs. (a) The Borrower shall make each payment required to be made by it hereunder or under any other Loan Document (whether of principal, interest or fees, or of amounts payable under Section 2.09, 2.10 or 2.11, or otherwise) prior to 1:00 p.m., New York City time, on the date when due, in immediately available funds, without set-off or counterclaim. Any amounts received after such time on any date may, in the discretion of the Administrative Agent, be deemed to have been received on the next succeeding Business Day for purposes of calculating interest thereon. All such payments shall be made to the Administrative Agent at its offices at Merrill Lynch World Headquarters, North Tower, World Financial Center, New York, New York 10281-1201, except that payments pursuant to Sections 2.09, 2.10, 2.11 and 9.03 shall be made directly to the Persons entitled thereto and payments pursuant to other Loan Documents shall be made

50

to the Persons specified therein. The Administrative Agent shall distribute any such payments received by it for the account of any other Person to the appropriate recipient promptly following receipt thereof. If any payment under any Loan Document shall be due on a day that is not a Business Day, the date for payment shall be extended to the next succeeding Business Day and, in the case of any payment accruing interest, interest thereon shall be payable for the period of such extension. All payments under each Loan Document shall be made in dollars.

(b) If at any time insufficient funds are received by and available to the Administrative Agent to pay fully all amounts of principal, interest and fees then due hereunder, such funds shall be applied (i) first, towards payment of interest and fees then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of interest and fees then due to such parties, and (ii) second, towards payment of principal then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of principal then due to such parties.

(c) If any Lender shall, by exercising any right of set-off or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of its Loans resulting in such Lender receiving payment of a greater proportion of the aggregate amount of its Loans and accrued interest thereon than the proportion received by any other Lender, then the Lender receiving such greater proportion shall purchase (for cash at face value) participations in the Loans of the other Lenders to the extent necessary so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Loans; provided that (i) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest, and (ii) the provisions of this paragraph shall not be construed to apply to any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans to any assignee or participant, other than to Level 3 or any Subsidiary or Affiliate thereof (as to which the provisions of this paragraph shall apply). The Borrower consents to the foregoing and agrees, to the extent it may effectively do so under applicable law, that any Lender acquiring a participation in an obligation owed by it pursuant to the foregoing arrangements may exercise against the Borrower rights of set-off and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of the Borrower in the amount of such participation.

(d) Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Administrative Agent for the account of the Lenders that the Borrower will not make such payment, the Administrative Agent may assume that the Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Lenders the amount due. In such event, if the Borrower has not in fact made such payment, then each of the Lenders severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the

51

date of payment to the Administrative Agent, at the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation.

(e) If any Lender shall fail to make any payment required to be made by it hereunder, then the Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), apply any amounts thereafter received by the Administrative Agent for the account of such Lender to satisfy such Lender’s obligations until all such unsatisfied obligations are fully paid.

SECTION 2.13. Mitigation Obligations; Replacement of Lenders. (a) If any Lender requests compensation under Section 2.09, or if the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.11, then such Lender shall use reasonable efforts to designate a different lending office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates if, in the judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 2.09 or 2.11, as the case may be, in the future and (ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. Level 3 and the Borrower hereby agree to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment.

(b) If any Lender requests compensation under Section 2.09 (other than paragraph (a) of such Section), or if the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.11, if any Lender defaults in its obligation to fund Loans hereunder or under the circumstances contemplated by Section 9.02(d), Level 3 may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in Section 9.04), all its interests, rights and obligations under this Agreement to an assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided that (i) Level 3 shall have received the prior written consent of the Administrative Agent, which consent shall not unreasonably be withheld, (ii) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans, accrued interest thereon, accrued fees and all other amounts payable to it hereunder, from the assignee (to the extent of such outstanding principal and accrued interest and fees) or Level 3 or the Borrower (in the case of all other amounts) and (iii) in the case of any such assignment resulting from a claim for compensation under Section 2.09 or payments required to be made pursuant to Section 2.11, such assignment will result in a reduction in such compensation or payments. A Lender shall not be required to make any such assignment and delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling Level 3 to require such assignment and delegation cease to apply.

52

ARTICLE III

SECTION 3.01. Organization; Powers. Each of Level 3, the Borrower and each Material Subsidiary of Level 3 is duly organized, validly existing and in good standing under the laws of the jurisdiction of its organization, has all requisite power and authority to carry on its business as now conducted and, except where the failure to do so, individually or in the aggregate, would not constitute or result in a Material Adverse Effect, is qualified to do business in, and is in good standing in, every jurisdiction where such qualification is required.

SECTION 3.02. Authorization; Enforceability. The Transactions to be entered into by each Loan Party on the Effective Date are within such Loan Party’s powers and have been duly authorized by all necessary corporate or other action and, if required, stockholder or member action. This Agreement has been duly executed and delivered by Level 3 and the Borrower and constitutes, and each other Loan Document to which any Loan Party is to be a party, when executed by and delivered by such Loan Party, will constitute, a legal, valid and binding obligation of such Loan Party, enforceable in accordance with its terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium or other laws affecting creditors’ rights generally and subject to general principles of equity, regardless of whether considered in a proceeding in equity or at law.

SECTION 3.03. Governmental Approvals; No Conflicts. The Transactions (a) do not require any consent or approval of, registration or filing with, or any other action by, any Governmental Authority, except such as are contemplated to be taken to satisfy the Guarantee Permit Condition and the Collateral Permit Condition and such as have been obtained or made and are in full force and effect and filings necessary to perfect Liens created under the Loan Documents, (b) will not violate the charter, by-laws or other organizational documents of Level 3 or any of the Loan Parties and will not violate, except for any violation which would not constitute or result in a Material Adverse Effect, (i) any applicable law or regulation of a type typically applicable to transactions of the type contemplated by the Transactions, (ii) any material order of any Governmental Authority, (c) will not violate the Parent’s Indentures, the Subordinated Indentures or the Financing Inc.

(a) The Lenders have been given access to Level 3’s consolidated balance sheet and statements of income, stockholders equity and cash flows as of and for the fiscal year ended December 31, 2006, reported on by KPMG LLP, an independent public accounting firm. Such financial statements present fairly in all material respects the financial position and results of operations and cash flows of Level 3 and its consolidated Subsidiaries as of such date and for such period in accordance with GAAP.

53

(b) Except for the Disclosed Matters, after giving effect to the Transactions, none of Level 3 or its Subsidiaries will have, as of the Effective Date, any contingent liabilities, unusual long-term commitments or unrealized losses which would constitute or result in a Material Adverse Effect.

(c) Except as may be disclosed in Level 3’s reports and filings under the Exchange Act filed or furnished since January 1, 2007 and prior to March 12, 2007 and available on the Securities and Exchange Commission’s website on the internet at www.sec.gov prior to the Effective Date, since December 31, 2006, there has been no material adverse change in the business, assets, operations or condition, financial or otherwise, of Level 3 and its Subsidiaries, taken as a whole which would constitute or result in a Material Adverse Effect.

SECTION 3.05. Properties. Each of Level 3, the Borrower and each Subsidiary of Level 3 has good title to, or valid leasehold interests in, all its real and personal property material to its business, except for minor defects in title that do not interfere with its ability to conduct its business as currently conducted or to utilize such properties for their intended purposes and such defects as would not constitute or result in a Material Adverse Effect.

SECTION 3.06. Litigation and Environmental Matters. (a) There are no actions, suits or proceedings by or before any arbitrator or Governmental Authority pending against or, to the knowledge of Level 3 or the Borrower, threatened against or affecting Level 3, the Borrower or any Material Subsidiary of Level 3 (i) as to which there is a reasonable possibility of an adverse determination and that, if adversely determined, would, individually or in the aggregate, constitute or result in a Material Adverse Effect (other than the Disclosed Matters) or (ii) that involve any of the Loan Documents or the Transactions.

(b) Except for the Disclosed Matters and except with respect to any other matters that, individually or in the aggregate, would not constitute or result in a Material Adverse Effect, none of Level 3, the Borrower or any of the Subsidiaries of Level 3 (i) has failed to comply with any Environmental Law or to obtain, maintain or comply with any permit, license or other approval required under any Environmental Law, (ii) has become subject to any Environmental Liability, (iii) has received notice of any claim with respect to any Environmental Liability or (iv) knows of any basis for any Environmental Liability.

SECTION 3.07. Compliance with Laws and Agreements. Level 3, the Borrower and each of the Subsidiaries of Level 3 is in compliance with all laws, regulations and orders of any Governmental Authority applicable to it or its property and all indentures, agreements and other instruments binding upon it or its property, except where the failure to do so, individually or in the aggregate, would not constitute or result in a Material Adverse Effect. No Default has occurred and is continuing.

54

SECTION 3.08. Investment Company Status. Neither Level 3 nor any of the Loan Parties is an “investment company” or is controlled by an entity that is an “investment company” as defined in, or subject to regulation under, the Investment Company Act of 1940.

SECTION 3.09. Taxes. Level 3, the Borrower and each of the Material Subsidiaries of Level 3 has timely filed or caused to be filed all tax returns and reports required to have been filed and has paid or caused to be paid all Taxes required to have been paid by it, except (a) Taxes that are being contested in good faith by appropriate proceedings and for which Level 3, the Borrower or such Subsidiary, as applicable, has set aside on its books adequate reserves or (b) to the extent that the failure to do so would not constitute or result in a Material Adverse Effect.

SECTION 3.10. ERISA. No ERISA Event has occurred or is reasonably expected to occur that, when taken together with all other such ERISA Events for which liability is reasonably expected to occur, would constitute or result in a Material Adverse Effect. The present value of all accumulated benefit obligations under each Plan (based on the assumptions used for purposes of Statement of Financial Accounting Standards No. 87) did not, as of the date of the most recent financial statements reflecting such amounts, exceed the fair market value of the assets of such Plan by an amount that would constitute or result in a Material Adverse Effect, and the present value of all accumulated benefit obligations of all underfunded Plans (based on the assumptions used for purposes of Statement of Financial Accounting Standards No. 87) did not, as of the date of the most recent financial statements reflecting such amounts, exceed the fair market value of the assets of all such underfunded Plans by an amount that would constitute or result in a Material Adverse Effect.

SECTION 3.11. Disclosure. None of the reports, financial statements, certificates or information furnished by or on behalf of any Loan Party to the Administrative Agent or any Lender in connection with the negotiation of this Agreement or any other Loan Document or delivered hereunder or thereunder (as modified or supplemented by other information so furnished), contains any material misstatement of fact or omits to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.

SECTION 3.12. Subsidiaries. Schedule 3.12 sets forth the name of, and the ownership interest of Level 3 in, each domestic Material Subsidiary.

SECTION 3.13. Insurance. Schedule 3.13 sets forth a description of all insurance maintained by or on behalf of Level 3, the Borrower and the Material Subsidiaries of Level 3 as of the Effective Date. To the knowledge of Level 3, such insurance complies with the requirements of Section 5.07.

SECTION 3.14. Labor Matters. As of the Effective Date, there are no material strikes, lockouts or slowdowns against Level 3, the Borrower or any Subsidiary of Level 3 pending or, to the knowledge of Level 3 or the Borrower, threatened which would constitute or result in a Material Adverse Effect. The consummation of the

55

SECTION 5.07. Insurance. Each of Level 3 and the Borrower will, and will cause each of the Restricted Subsidiaries to, keep all of their respective properties

62

which are of an insurable nature insured with insurers, believed by the Borrower to be responsible, against loss or damage to the extent that property of a similar character is usually insured by companies similarly situated and owning like properties. Level 3 will furnish to the Lenders, upon the reasonable request of the Administrative Agent, but not more than once during any calendar year unless a Default or an Event of Default has occurred and is continuing, information in reasonable detail as to the insurance so maintained.

SECTION 5.08. Casualty and Condemnation. Level 3 (a) will furnish to the Administrative Agent prompt written notice of any casualty or other insured damage to any portion of any Collateral or the commencement of any action or proceeding for the taking of any Collateral or any part thereof or interest therein under power of eminent domain or by condemnation or similar proceeding in each case only where Level 3 estimates in good faith that the expected proceeds from insurance, condemnation awards or otherwise will exceed $25,000,000 and (b) will ensure that the Net Available Proceeds of any such event (whether in the form of insurance proceeds, condemnation awards or otherwise) are collected and applied in accordance with the applicable provisions of this Agreement and the Security Documents.

SECTION 5.10. Compliance with Laws. Each of Level 3 and the Borrower will, and will cause each of the Restricted Subsidiaries of Level 3 to, comply with all laws (including the Communications Act), rules, regulations and orders of any Governmental Authority applicable to it or its property (including obligations under Licenses), except where the failure to do so, individually or in the aggregate, would not constitute or result in a Material Adverse Effect.

SECTION 5.11. Use of Proceeds. The proceeds of the Loans will be (a) used to refinance the Existing Term Loans and (b) to the extent of the remaining proceeds, advanced by the Borrower to Level 3 LLC against delivery of the Loan Proceeds Note.

SECTION 5.12. Guarantee and Collateral Requirement; Further Assurances. Level 3 and the Borrower will cause the Guarantee and Collateral Requirement to be and remain satisfied at all times. Without limiting the foregoing, Level 3 and the Borrower will, and will cause each Subsidiary of Level 3 to, execute any and all documents, financing statements, agreements and instruments, and take all other actions (including the filing of financing statements and other documents), which shall be required under any applicable United States law, or which the Collateral Agent may reasonably request, to effectuate the transactions contemplated by the Loan Documents or

63

to grant, preserve, protect or perfect the Liens created or intended to be created by the Loan Documents or the validity or priority of any such Lien, all at the expense of the Loan Parties. Level 3 and the Borrower also agree to provide to the Collateral Agent, from time to time upon request, evidence reasonably satisfactory to the Collateral Agent as to the perfection of the Liens created or intended to be created by the Loan Documents.

SECTION 5.13. Guarantee Permit Condition and Collateral Permit Condition. (a) Each of Level 3 and the Borrower will endeavor, and cause each Regulated Grantor and each Regulated Guarantor to endeavor, in good faith using commercially reasonable efforts to (i) (A) cause the Collateral Permit Condition to be satisfied with respect to such Regulated Grantor and (B) cause the Guarantee Permit Condition to be satisfied with respect to such Regulated Guarantor, in each case at the earliest practicable date and (ii) obtain the material (as determined in good faith by the General Counsel of Level 3) authorizations and consents of Federal and State Authorities required to cause any Restricted Subsidiary to become a Guarantor as required by Sections 6.01(d) and 6.02(d). For purposes of this Section, the requirement that Level 3, the Borrower or any Subsidiary of Level 3 use “commercially reasonable efforts” shall not be deemed to require it to make material payments in excess of normal fees and costs to or at the direction of Governmental Authorities or to change the manner in which it conducts its business in any respect that the management of Level 3 shall determine in good faith to be adverse or materially burdensome. Upon the reasonable request of Level 3 or the Borrower, the Administrative Agent and the Lenders will cooperate with Level 3 and the Borrower as necessary to enable them to comply with their obligations under this Section.

(b) If Level 3 shall determine that Level 3 LLC is able, consistent with applicable law, to create Liens on any Collateral owned by it and located in any jurisdiction located in the United States to secure the Loan Proceeds Note prior to the satisfaction by it of the Collateral Permit Condition, it will cause Level 3 LLC promptly to create and perfect such Liens on terms and under documentation reasonably satisfactory to Level 3 and the Collateral Agent.

(v) shall not, and shall not permit any Restricted Subsidiary to, issue, transfer, convey, sell or otherwise dispose of Capital Stock of any Restricted Subsidiary to a Person other than Level 3 or another Restricted Subsidiary if the result thereof is that such Restricted Subsidiary shall cease to be a Restricted Subsidiary, in which event the amount of such “Restricted Payment” shall be the Fair Market Value of the remaining interest, if any, in such former Restricted Subsidiary held by Level 3 and the other Restricted Subsidiaries (each of clauses (i) through (v) being a “ Restricted Payment ”)

if:

(b) Notwithstanding the foregoing limitation,

(i) Level 3 may pay any dividend on Capital Stock of any class of Level 3 within 60 days after the declaration thereof if, on the date when the dividend was declared, Level 3 could have paid such dividend in accordance with the foregoing provisions; provided , however , that at the time of such payment of such dividend, no other Event of Default shall have occurred and be continuing (or result therefrom);

(ii) Level 3 may repurchase any shares of its Common Stock or options to acquire its Common Stock from Persons who were formerly directors, officers or employees of Level 3 or any of its Subsidiaries or other Affiliates in an amount not to exceed $3,000,000 in any 12-month period;

SECTION 6.07. Limitation on Asset Dispositions. (a) Level 3 shall not, and shall not permit any Restricted Subsidiary to, make any Asset Disposition unless: (i) Level 3 or the Restricted Subsidiary, as the case may be, receives consideration for such disposition at least equal to the Fair Market Value for the Property sold or disposed of as determined by the Board of Directors of Level 3 in good faith and evidenced by a Board Resolution of Level 3; and (ii) at least 75% of the consideration for such disposition consists of cash or Cash Equivalents or the assumption of Indebtedness of the Borrower or any Borrower Restricted Subsidiary (other than Indebtedness of the Borrower that is subordinated to the Obligations or Indebtedness of any Borrower Restricted Subsidiary that is subordinated to the Obligations of such Borrower Restricted Subsidiary) and release of the Borrower and all Borrower Restricted Subsidiaries from all liability on the Indebtedness assumed (or if less than 75%, the remainder of such consideration consists of Telecommunications/IS Assets); provided , however , that, to the extent such disposition involves Special Assets, all or any portion of the consideration may, at Level 3’s election, consist of Property other than cash, Cash Equivalents or the assumption of Indebtedness or Telecommunications/IS Assets.

(b) If the Net Available Proceeds from any Asset Disposition (or any series of related Asset Dispositions) consisting of Property that is Collateral or Property that would be required to become Collateral following the satisfaction of the Guarantee Permit Condition and the Collateral Permit Condition exceed $20,000,000, the Borrower shall deposit an amount in cash or cash equivalents equal to such Net Available Proceeds (which such amount shall thereafter constitute the Net Available Proceeds of such Asset Disposition or related Asset Dispositions) into a deposit account in which the Collateral Agent has a perfected security interest in favor of the Lenders. Prior to the time a Notice of Default shall have been delivered to the Borrower pursuant to Article VII, the Borrower may withdraw such Net Available Proceeds, and the Collateral Agent, at the Request of the Borrower, shall take all actions necessary, at the expense of the Borrower, to promptly release the security interest in such Net Available Proceeds (i) to permit Level 3 or a Restricted Subsidiary to reinvest such Net Available Proceeds in Telecommunications/IS Assets, (ii) to permit the Borrower to repay the Loans in accordance with Section 2.05(b) or (iii) following any prepayment of the Loans as required by Section 2.05(b), with respect to any such Net Available Proceeds that have been rejected by Declining Lenders pursuant to Section 2.05(e), to Level 3 or any Restricted Subsidiary for any purpose.

82

(c) The Net Available Proceeds (or any portion thereof) from Asset Dispositions may be applied by Level 3 or a Restricted Subsidiary, to the extent Level 3 or such Restricted Subsidiary elects: (1) to permanently prepay Borrowings in accordance with Section 2.05(b) or (c) or (2) to reinvest in Telecommunications/IS Assets (including by means of an Investment in Telecommunications/IS Assets by a Restricted Subsidiary with Net Available Proceeds received by Level 3 or another Restricted Subsidiary). Level 3 shall not, and shall not permit any Restricted Subsidiary, to acquire any Telecommunications/IS Assets with the Net Available Proceeds of any Asset Disposition consisting of Collateral or Property that would be required to become Collateral following the satisfaction of the Guarantee Permit Condition and the Collateral Permit Condition unless such Telecommunications/IS Assets are Collateral or Property that would be required to become Collateral following the satisfaction of the Guarantee Permit Condition and the Collateral Permit Condition. Any Net Available Proceeds from an Asset Disposition not applied in accordance with paragraph (b) within 330 days (or, in the case of a disposition of Special Assets identified in clause (a) of the definition thereof in which the Net Available Proceeds exceed $500,000,000, 510 days) from the date of the receipt of such Net Available Proceeds shall constitute “ Excess Proceeds .” The Borrower shall apply such Excess Proceeds to the extent and in the manner required by Section 2.05.

(d) (1) The Borrower shall not, and shall not permit any Borrower Restricted Subsidiary, to sell, transfer, lease or otherwise dispose of any Property that is Collateral or that would be required to become Collateral following the satisfaction of the Collateral Permit Condition to a Subsidiary of Level 3 (other than a Subsidiary that is a Guarantor and a Grantor or that will become a Guarantor and a Grantor following satisfaction of the Guarantee Permit Condition and the Collateral Permit Condition), and (2) Level 3 shall not designate as an Unrestricted Subsidiary any Borrower Restricted Subsidiary that owns, directly or indirectly, any Property that is Collateral or that would be required to become Collateral following the satisfaction of the Collateral Permit Condition unless either:

(A) (1) in the case of a sale, transfer, lease or other disposition, the Borrower or such Borrower Restricted Subsidiary receives consideration for such sale, transfer, lease or other disposition at least equal to the Fair Market Value of such Property (which, in the case of the Offering Proceeds Notes, any other intercompany Indebtedness or the Loan Proceeds Note, is the principal amount of such Offering Proceeds Note, such Indebtedness or the Loan Proceeds Note, as applicable, and any accrued and unpaid interest thereon), and

(2) in the case of a sale, transfer, lease or other disposition, the consideration consists of 100% in cash or Cash Equivalents; or

83

(B) such transaction:

(1) is desirable in the conduct of the business of Level 3 and its Subsidiaries taken as a whole (as conclusively determined by the Board of Directors of Level 3), and

(2) (i) in the case of a sale, transfer, lease or other disposition in which the consideration does not consist of 100% cash or Cash Equivalents, the Fair Market Value of the Property that is Collateral so sold, transferred, leased or disposed of (net of any cash or Cash Equivalents received by the Borrower or such Borrower Restricted Subsidiary in respect of such Collateral), or (ii) in the case of a designation of a Borrower Restricted Subsidiary as an Unrestricted Subsidiary, the Fair Market Value of all Property that is Collateral owned, directly or indirectly, by such Borrower Restricted Subsidiary at the time it is designated an Unrestricted Subsidiary, when taken together with the Collateral Release Amount (determined prior to such sale, lease, transfer or other disposition or designation as an Unrestricted Subsidiary), does not exceed 5.0% of Consolidated Tangible Assets as determined at the time of such sale, lease, transfer or other disposition or designation as an Unrestricted Subsidiary, on the basis of the most recent consolidated balance sheet available to Level 3 (as conclusively determined in good faith by the Chief Financial Officer of Level 3).

For purposes of this Section 6.07(d), “ Collateral Release Amount ” means an amount equal to:

(1) the sum of (x) the Fair Market Value of any Property that constituted Collateral previously sold, transferred, leased or otherwise disposed of pursuant to this Section 6.07(d) for consideration not consisting of 100% cash or Cash Equivalents (net of any cash or Cash Equivalents received by the transferor in consideration for such sale, transfer, lease or other disposition) plus (y) the Fair Market Value of all Property that constituted Collateral held directly or indirectly by each Borrower Restricted Subsidiary previously designated as an Unrestricted Subsidiary pursuant to this Section 6.07(d), minus

(2) the sum of, without duplication, (x) the amount of any cash or Cash Equivalents received by the Borrower or a Borrower Restricted Subsidiary in repayment of principal or as a return of capital from an Investment made pursuant to clause (B) of this Section 6.07(d) plus (y) the amount of any cash or Cash Equivalents received by the Borrower or a Borrower Restricted Subsidiary from a Borrower Restricted Subsidiary designated as an Unrestricted Subsidiary pursuant to this Section 6.07(d) representing a return of capital, in the case of clauses (x) and (y), to the extent such cash or Cash Equivalents were treated as Net Available Proceeds from an Asset Disposition, plus (z) the Fair Market Value

84

(determined at the time that such Property again becomes Collateral in accordance with the Security Documents) of any Property which had ceased to be Collateral pursuant to this Section 6.07(d) and thereafter became Collateral in accordance with the terms of the Security Documents.

In the event of (a) a transfer of Property that constitutes Collateral made in accordance with this Section 6.07(d), such Property shall be released from any Lien to which it is subject pursuant to the Security Documents in accordance with the procedures in Section 9.14 or (b) the designation of a Restricted Subsidiary as an Unrestricted Subsidiary in compliance with this Section 6.07(d), such Restricted Subsidiary shall, by delivery of documentation providing for such release in form satisfactory to the Administrative Agent, be released from any Guarantee (in the case of a Guarantor) and its obligations under the Collateral Agreement (in the case of a Grantor) previously made by such Subsidiary.

(e) The Borrower shall not, and shall not permit any Borrower Restricted Subsidiary to, sell, transfer, lease or otherwise dispose of any Property that does not constitute Collateral to Level 3 or any Sister Restricted Subsidiary unless (i) the Borrower or such Borrower Restricted Subsidiary receives consideration for such sale, transfer, lease or other disposition at least equal to the Fair Market Value of such Property and (ii) the consideration consists of either (A) 100% in cash or Cash Equivalents or (B) Indebtedness of Level 3 or the Restricted Subsidiary to which Property was transferred that is secured by a Lien on such transferred Property. Level 3 or the Restricted Subsidiary to which Property was transferred for consideration consisting of Indebtedness that is secured by a Lien on such Property in accordance with clause (ii)(B) of the prior sentence may substitute the Lien on such Property with a Lien on other Property (including any Property owned by the Borrower or a Borrower Restricted Subsidiary) that, as determined by the Board of Directors of Level 3 in good faith and evidenced by a Board Resolution of Level 3 filed with the Agent upon request of the Agent, has a Fair Market Value of no less than the Fair Market Value of the Property for which the substitution is made at the time of the substitution. The provisions of this paragraph do not apply to (a) dividends and distributions, (b) loans or advances and (c) purchases of services or goods.

SECTION 6.08. Limitation on Issuance and Sales of Capital Stock of Restricted Subsidiaries. Level 3 shall at all times own all the issued and outstanding Capital Stock of the Borrower.

At the time of any Designation of any Subsidiary as an Unrestricted Subsidiary, such Subsidiary shall not own any Capital Stock of Level 3 or any Restricted Subsidiary. In addition, neither Level 3 nor any Restricted Subsidiary shall at any time (x) provide credit support for, or a Guarantee of, any Indebtedness of any Unrestricted Subsidiary (including any undertaking, agreement or instrument evidencing such Indebtedness); provided , however , that Level 3 or a Restricted Subsidiary may pledge Capital Stock or Indebtedness of any Unrestricted Subsidiary on a nonrecourse basis such that the pledgee has no claim whatsoever against Level 3 other than to obtain such pledged Capital Stock or Indebtedness, (y) be directly or indirectly liable for any Indebtedness of any Unrestricted Subsidiary or (z) be directly or indirectly liable for any Indebtedness which provides that the holder thereof may (upon notice, lapse of time or both) declare a default thereon or cause the payment thereof to be accelerated or payable prior to its final scheduled maturity upon the occurrence of a default with respect to any Indebtedness, Lien or other obligation of any Unrestricted Subsidiary (including any right to take enforcement action against such Unrestricted Subsidiary), except in the case of clause (x) or (y) to the extent permitted under Sections 6.03 and 6.09.

Unless Designated as an Unrestricted Subsidiary, any Person that becomes a Subsidiary of Level 3 will be classified as a Restricted Subsidiary; provided , however , that such Subsidiary shall not be designated as a Restricted Subsidiary and shall be automatically classified as an Unrestricted Subsidiary if either of the requirements set forth in clauses (a) and (b) of the immediately following paragraph will not be satisfied immediately following such classification. Except as provided in the first sentence of this Section 6.10, no Restricted Subsidiary may be redesignated as an Unrestricted Subsidiary.

A Designation may be revoked (a “ Revocation ”) by a Board Resolution of Level 3 delivered to the Administrative Agent, provided that Level 3 will not make any Revocation unless:

(a) no Default or Event of Default shall have occurred and be continuing at the time of and after giving effect to such Revocation; and

88

(b) all Liens and Indebtedness of such Unrestricted Subsidiary outstanding immediately following such Revocation would, if Incurred at such time, have been permitted to be Incurred at such time for all purposes of this Agreement.

All Designations and Revocations must be evidenced by Board Resolutions of Level 3 delivered to the Administrative Agent (i) certifying compliance with the foregoing provisions and (ii) giving the effective date of such Designation or Revocation. Upon Designation of a Restricted Subsidiary as an Unrestricted Subsidiary in compliance with this Section 6.10, such Restricted Subsidiary shall, by delivery of documentation providing for such release in form satisfactory to the Administrative Agent, be released from any Guarantee (in the case of a Guarantor) and its obligations under the Collateral Agreement (in the case of a Grantor) previously made by such Subsidiary.

SECTION 6.11. Limitation on Actions with respect to Existing Intercompany Obligations. Without the consent of the holders of at least two-thirds of the outstanding principal amount of the Loans:

(a) the Borrower shall not forgive or waive or fail to enforce any of its rights under any Offering Proceeds Note, the Loan Proceeds Note, any Financing Inc. Notes Supplemental Indenture, the Omnibus Offering Proceeds Note Subordination Agreement or any other agreement with Level 3 or any Restricted Subsidiary to subordinate a payment obligation on any Indebtedness to the prior payment in full in cash of all obligations with respect to the Loan Proceeds Note, a Loan Proceeds Note Guarantee, any Offering Proceeds Note or any Offering Proceeds Note Guarantee, and the Borrower and Level 3 LLC may not amend the Loan Proceeds Note, a Loan Proceeds Note Guarantee, any Offering Proceeds Note or any Offering Proceeds Note Guarantee, in a manner adverse to the Lenders; provided , however , that that in the event of an Event of Default of Level 3 LLC as described in clause (i) or (j) of Article VII, the principal then outstanding together with accrued interest thereon on the Loan Proceeds Note, each Offering Proceeds Note, the Loan Proceeds Note Guarantee and each Offering Proceeds Note Guarantee shall automatically become due and payable without presentment, demand, protest or other notice of any kind;

(b) in the event Level 3 LLC (or any successor obligor under the Loan Proceeds Note) repays all or a portion of the Loan Proceeds Note, the Borrower must prepay the Loans in a principal amount equal to the principal amount of the Loan Proceeds Note then repaid in accordance with, and if at such time permitted by, this Agreement; provided , however , that if at any time the principal amount of the Loan Proceeds Note is greater than the principal amount of the Loans that remains outstanding, Level 3 LLC (or any successor obligor under the Loan Proceeds Note) may repay or forgive or waive an amount of the Loan Proceeds Note equal to such excess without complying with this paragraph (b);

(c) Level 3 shall not, and shall not permit any Restricted Subsidiary to, provide any Lien on its Property for the benefit of, or any Guarantee (other than a similarly subordinated Guarantee) or other form of credit enhancement in respect

89

of, (i) the Parent Intercompany Note or (ii) any other intercompany note required by clause (vi) of paragraph (b) of Section 6.01 or clause (iv) of paragraph (b) of Section 6.02 to be subordinated to the prior payment in full in cash of all obligations with respect to the Loan Proceeds Note or a Loan Proceeds Note Guarantee, or take any other action with the purpose or effect of making the Parent Intercompany Note senior to or equal in right of payment with any Offering Proceeds Note or the Loan Proceeds Note;

(d) Level 3 shall not, and shall not permit any Restricted Subsidiary to, provide any Lien on its Property for the benefit of, or any Guarantee (other than a similarly subordinated Guarantee) or other form of credit enhancement in respect of, (i) any Offering Proceeds Note or (ii) any other intercompany note required by clause (vi) of paragraph (b) of Section 6.01 or clause (iv) of paragraph (b) of Section 6.02 to be subordinated to the prior payment in full in cash of all obligations with respect to the Loan Proceeds Note or a Loan Proceeds Note Guarantee, or take any other action with the purpose or effect of making any Offering Proceeds Note senior to or equal in right of payment with the Loan Proceeds Note;

(e) Level 3 and Level 3 LLC shall not amend the terms of the Parent Intercompany Note or any Offering Proceeds Note in a manner adverse to the Lenders, the determination of which shall be made by the Board of Directors of Level 3 acting in good faith and shall be evidenced by a Board Resolution of Level 3;

(f) Level 3, the Borrower and Level 3 LLC shall not amend any of the Financing Inc. Notes Supplemental Indentures or the Omnibus Offering Proceeds Note Subordination Agreement in a manner adverse to the Lenders and Level 3 or any Restricted Subsidiary and the Borrower shall not amend any other agreement between Level 3 or any Restricted Subsidiary and the Borrower to subordinate a payment obligation on any Indebtedness of Level 3 or any Restricted Subsidiary to the prior payment in full in cash of all obligations with respect to the Loan Proceeds Note, in each case, the determination of which shall be made by the Board of Directors of Level 3 acting in good faith and shall be evidenced by a Board Resolution of Level 3;

(g) unless an Event of Default has occurred and is continuing, Level 3 shall neither cause nor permit the Borrower to demand repayment of any Offering Proceeds Note prior to the satisfaction of the Guarantee Permit Condition and the Collateral Permit Condition; and

(h) Level 3 and the Borrower shall cause any Indebtedness of Level 3 LLC to Level 3 to be evidenced by either the Parent Intercompany Note or another duly executed promissory note that is pledged and delivered to the Collateral Agent within 3 Business Days of the Incurrence of such Indebtedness.

SECTION 6.12. Covenant Suspension. During any period of time (a “ Suspension Period ”) that (i) the ratings assigned to the Term Loan by both of the Rating Agencies are Investment Grade Ratings and (ii) no Default or Event of Default has occurred and is continuing, Level 3 and the Restricted Subsidiaries will not be subject to the covenants set forth in Sections 6.01, 6.02, 6.03, 6.04, 6.06(i)(a), 6.07, 6.08 (other than the first two sentences thereof), 6.09, 6.13(a)(3) and (4), 6.13(c)(3) and (4) and clause (b) of the first sentence of Section 6.10 (collectively, the “ Suspended Covenants ”). In the event that Level 3 and the Restricted Subsidiaries are not subject to the Suspended Covenants for any period of time as a result of the preceding sentence and, on any subsequent date (the “ Reversion Date ”), one or both of the Rating Agencies withdraws its ratings or downgrades the ratings assigned to the Loan below the required Investment Grade Ratings or a Default or Event of Default occurs and is continuing, then Level 3 and the Restricted Subsidiaries will thereafter again be subject to the Suspended Covenants and calculations of the amount available to be made as Restricted Payments under Section 6.03 will be made as though Section 6.03 had been in effect during the entire period of time from the Measurement Date. On the Reversion Date, all Indebtedness Incurred during the Suspension Period will be classified to have been Incurred pursuant to paragraph (a) of Section 6.01 or one of the clauses set forth in paragraph (b) of Section 6.01 or paragraph (a) of Section 6.02 or one of the clauses set forth in paragraph (b) of Section 6.02 (in each case to the extent such Indebtedness would be permitted to be Incurred thereunder as of the Reversion Date and after giving effect to Indebtedness Incurred prior to the Suspension Period and outstanding on the Reversion Date). To the extent such Indebtedness would not be permitted to be Incurred pursuant to paragraph (a) of Section 6.01 or one of the clauses set forth in paragraph (b) of Section 6.01 or paragraph (a) of Section 6.02 or one of the clauses set forth in paragraph (b) of Section 6.02, such Indebtedness will be deemed to have been outstanding on the Measurement Date, so that it is classified as permitted under Section 6.01(b)(v) or Section 6.02(b)(iii). If the Incurrence of any Indebtedness by a Restricted Subsidiary during the Suspension Period would have been prohibited or conditioned upon such Restricted Subsidiary entering into a Guarantee of the Obligations and a Loan Proceeds Note Guarantee had Section 6.01 and Section 6.02 been in effect at the time of such Incurrence, such Restricted Subsidiary shall enter into a Guarantee of the Obligations and a Loan Proceeds Note Guarantee that are senior to or pari passu with such Indebtedness within ten days after the Reversion Date. For purposes of determining compliance with Section 6.07 on the Reversion Date, the Net Available Proceeds from all Asset Dispositions not applied in accordance with the covenant will be deemed to be reset to zero. Notwithstanding the foregoing, neither (a) the continued existence, after the date of such withdrawal or downgrade, of facts and circumstances or obligations that were Incurred or otherwise came into existence during a Suspension Period nor (b) the performance of any such obligations, shall constitute a breach of any covenant set forth in the Agreement or cause a Default or Event of Default thereunder; provided , however , that (1) Level 3 and its Restricted Subsidiaries did not Incur or otherwise cause such facts and circumstances or obligations to exist in anticipation of a withdrawal or downgrade below investment grade, (2) Level 3 reasonably believed that such Incurrence or actions would not result in such a withdrawal or downgrade and (3) if so required each Restricted Subsidiary shall have entered into a Guarantee of the Obligations and a Loan Proceeds

91

Note Guarantee within the specified time period. For purposes of clauses (1) and (2) in the preceding sentence, anticipation and reasonable belief may be determined by Level 3 and shall be conclusively evidenced by a board resolution to such effect adopted in good faith by the Board of Directors of Level 3. In reaching their determination, the Board of Directors of Level 3 may, but need not, consult with the Rating Agencies.

In the event the institution serving as the Agent hereunder shall also be a Lender, it shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not the Agent, and such institution and its Affiliates may accept deposits from, lend money to and generally engage in any kind of business with Level 3, the Borrower or any Subsidiary or Affiliate thereof as if it were not the Agent hereunder.

The Agent shall not have any duties or obligations except those expressly set forth in the Loan Documents. Without limiting the generality of the foregoing, (a) the Agent shall not be subject to any fiduciary or other implied duties, regardless of whether

99

a Default has occurred and is continuing, (b) the Agent shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated by the Loan Documents that the Agent is required to exercise in writing by the Required Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 9.02), and shall not have any duty to take any action or exercise any powers that would result in the incurrence by it of costs or expenses unless arrangements satisfactory to it to ensure the prompt payment of all such costs or expenses shall have been made by the Lenders, and (c) except as expressly set forth in the Loan Documents, the Agent shall not have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to Level 3, the Borrower or any of the Subsidiaries of Level 3 that is communicated to or obtained by the institution serving as Agent or any of its Affiliates in any capacity. The Agent shall not be liable for any action taken or not taken by it with the consent or at the request of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 9.02) or in the absence of its own gross negligence or willful misconduct. The Agent shall be deemed not to have knowledge of any Default unless and until written notice thereof is given to the Agent by Level 3, the Borrower or a Lender, and the Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with any Loan Document, (ii) the contents of any certificate, report or other document delivered thereunder or in connection therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth in any Loan Document, (iv) the validity, enforceability, effectiveness or genuineness of any Loan Document or any other agreement, instrument or document, or (v) the satisfaction of any condition set forth in Article IV or elsewhere in any Loan Document, other than to confirm receipt of items expressly required to be delivered to the Agent. As to any matters not expressly provided for by this Agreement and the other Loan Documents (including enforcement or collection), the Administrative Agent and the Collateral Agent shall not be required to exercise any discretion or take any action, but shall be required to act or to refrain from acting (and shall be fully protected in so acting or refraining from acting) upon the instructions of the Requisite Lenders, and such instructions shall be binding upon all Lenders, provided , however , that the Administrative Agent and the Collateral Agent shall not be required to take any action that (i) the Administrative Agent or the Collateral Agent in good faith believes exposes it to personal liability unless it receives an indemnification satisfactory to it from the Lenders with respect to such action or (ii) is contrary to this Agreement or applicable law.

The Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing believed by it to be genuine and to have been signed or sent by the proper Person. The Agent also may rely upon any statement made to it orally or by telephone and believed by it to be made by the proper Person, and shall not incur any liability for relying thereon. The Agent may consult with legal counsel (who may be counsel for Level 3 or the Borrower), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.

100

The Agent may perform any and all its duties and exercise its rights and powers by or through any one or more sub-agents appointed by the Agent. The Agent and any such sub-agent may perform any and all its duties and exercise its rights and powers through their respective Related Parties. The exculpatory provisions of the preceding paragraphs shall apply to any such sub-agent and to the Related Parties of each Agent and any such sub-agent, and shall apply to their respective activities in connection with the syndication of the credit facilities provided for herein as well as activities as Agent.

Subject to the appointment and acceptance of a successor as provided in this paragraph, the Agent may resign at any time by notifying the Lenders and Level 3. Upon any such resignation, the Required Lenders shall have the right, with, so long as no Default or Event of Default shall have occurred and be continuing, the consent of Level 3 (which consent shall not be unreasonably withheld or delayed) to appoint a successor. If no successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within 30 days after the retiring Agent gives notice of its resignation, then the retiring Agent may, on behalf of the Lenders, appoint a successor Agent which shall be a Lender or a bank with an office in New York, New York, or an Affiliate of such Lender or any such bank. Upon the acceptance of its appointment as Agent hereunder by a successor, such successor shall succeed to and become vested with all the rights, powers, privileges and duties of the retiring Agent, and the retiring Agent shall be discharged from its duties and obligations hereunder. The fees payable by Level 3 and the Borrower to a successor Agent shall be the same as those payable to its predecessor unless otherwise agreed with such successor. After the Agent’s resignation hereunder, the provisions of this Article and Section 9.03 shall continue in effect for the benefit of such retiring Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while it was acting as Agent.

Each Lender acknowledges that it has, independently and without reliance upon the Agent or any other Lender and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender also acknowledges that it will, independently and without reliance upon the Agent or any other Lender and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any other Loan Document or related agreement or any document furnished hereunder or thereunder.

SECTION 9.02. Waivers; Amendments; Addition of Term or Revolving Tranches. (a) No failure or delay by the Administrative Agent or any Lender in exercising any right or power hereunder or under any other Loan Document shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of the Administrative Agent and the Lenders hereunder and under the other Loan Documents are cumulative and are not exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of any Loan Document or consent to any departure by any Loan Party therefrom shall in any event be effective unless the same shall be permitted by paragraph (b) of this Section, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. Without limiting the generality of the foregoing, the making of a Loan shall not be construed as a waiver of any Default, regardless of whether the Administrative Agent or any Lender may have had notice or knowledge of such Default at the time.

(b) Except as provided in paragraph (d) of this Section, none of this Agreement, any other Loan Document or any provision hereof or thereof may be waived, amended or modified except, in the case of this Agreement, pursuant to an agreement or agreements in writing entered into by Level 3, the Borrower and the Required Lenders or,

102

in the case of any other Loan Document, pursuant to an agreement or agreements in writing entered into by the Administrative Agent and the Loan Party or Loan Parties that are parties thereto, in each case with the consent of the Required Lenders; provided that no such agreement shall (i) increase the Commitment of or impose additional obligations on any Lender without the written consent of such Lender, (ii) reduce the principal amount of any Loan or reduce the rate of interest thereon without the written consent of each Lender affected thereby, (iii) postpone the scheduled date of payment of the principal amount of any Loan or any interest thereon, or reduce the amount of, waive or excuse any such payment, without the written consent of each Lender affected thereby, (iv) change Section 2.12(b) or (c) in a manner that would alter the pro rata sharing of payments required thereby without the written consent of each Lender (except as provided in paragraph (d) of this Section), (v) change any of the provisions of this Section or the definition of “Required Lenders” or any other provision of any Loan Document specifying the number or percentage of Lenders required to waive, amend or modify any rights thereunder or make any determination or grant any consent thereunder, without the written consent of each Lender (except as provided in paragraph (d) of this Section), (vi) release Level 3 or any other Guarantor from its Guarantee of the Obligations under the Guarantee Agreement (except as expressly provided in Sections 6.07, 6.08, 6.10 or 9.14 or in the Guarantee Agreement), or limit its liability in respect of any such Guarantee, without the written consent of each Lender, (vii) release all or any substantial part of the Collateral from the Liens of the Security Documents (except as expressly provided in Sections 6.07, 6.08, 6.10 or 9.14 or in Collateral Agreement), or subordinate such Liens, without the written consent of each Lender or (viii) except to the extent necessary to comply with applicable law, amend or modify Section 9.04 in a manner that would by the terms of such amendment or waiver, as applicable, restrict the ability of the Lenders to make assignments, without the written consent of each Lender, provided further that no such agreement shall amend, modify or otherwise affect the rights or duties of the Administrative Agent, without the prior written consent of the Administrative Agent.

(c) If, in connection with any proposed change, waiver, discharge or termination of any of the provisions of this Agreement referred to in any of clauses (i) through (vii) of the first proviso in paragraph (b) of this Section, the consent of the Required Lenders shall be obtained but the consent of one or more other Lenders whose consent is sought shall not be obtained, then the Borrower shall have the right, so long as all non-consenting Lenders whose individual consents are sought are treated as described in either clauses (A) or (B) below, to either (A) replace each such non-consenting Lender or Lenders with one or more replacement Lenders in accordance with the provisions of Section 2.13(b) so long as, at the time of such replacement, each such replacement Lender consents to the proposed change, waiver, discharge or termination or (B) repay the outstanding Loans of each such non-consenting Lender in accordance with Sections 2.05(a) and 2.10; provided that, unless the Loans that are repaid pursuant to preceding clause (B) are immediately replaced in full at such time through the addition of new Lenders or the increase of the outstanding Loans of existing Lenders (who in each case must specifically consent thereto), then in the case of any action pursuant to preceding clause (B) each Lender (determined after giving effect to the proposed action) shall specifically consent thereto.

103

(d) Notwithstanding anything in paragraph (b) of this Section to the contrary, this Agreement and the other Loan Documents may be amended at any time and from time to time to establish revolving credit commitments or one or more additional classes of term loans by an agreement in writing entered into by Level 3, the Borrower, the Administrative Agent, the Collateral Agent and each person (including any Lender) that shall agree to provide such a revolving credit commitment or make a term loan of any class so established (but without the consent of any other Lender), and each such person that shall not already be a Lender shall, at the time such agreement becomes effective, become a Lender with the same effect as if it had originally been a Lender under this Agreement with the revolving credit commitment and/or term loans set forth in such agreement; provided that the aggregate outstanding principal amount of the revolving credit commitments and term loans of all classes established pursuant to this paragraph shall at no time exceed the maximum principal amount of the Indebtedness permitted to be incurred at such time under Section 6.01(b)(ii) and 6.02(b)(ii)). Any such agreement shall amend the provisions of this Agreement and the other Loan Documents to set forth the terms of the revolving credit commitments or class of term loans established thereby (including the amount and final maturity thereof (which, in the case of any class of term loans, shall not be earlier than the Maturity Date), any provisions relating to amortization or mandatory prepayments or offers to prepay (it being agreed that not more than 1% of the aggregate principal amount of the term loans of any class shall amortize during any calendar year prior to the Maturity Date and that provisions for mandatory prepayments of and offers to prepay the term loans of any class may require such term loans to be prepaid or offered the right to be prepaid ratably with the Loans but shall not include any additional mandatory prepayment rights), the interest to accrue and be payable thereon and any fees to be payable in respect thereof) and to effect such other changes (including changes to the provisions of this Section, Section 2.12 and the definition of “Required Lenders” and changes to provide for a note of Level 3 LLC evidencing the advance of the proceeds of any loans) as Level 3, the Borrower and the Administrative Agent shall deem necessary or advisable in connection with the establishment of any such revolving credit commitments or class of term loans; provided that no such agreement shall (i) effect any change described in any of clauses (i), (ii), (iii), (vi) or (vii) of paragraph (b) of this Section without the consent of each person required to consent to such change under such clause (it being agreed, however, that the establishment of any revolving commitment or class of term loans will not, of itself, be deemed to effect any of the changes described in clauses (vi) or (vii) of such paragraph (b)), or (ii) amend Article V, VI or VII to establish any affirmative or negative covenant, Event of Default or remedy that by its terms benefits any such revolving credit commitments or class of term loans but not the Loans without the prior written consent of Lenders holding a majority in interest of the Loans. Without limiting the foregoing, a Qualified Receivable Facility permitted by Sections 6.01 and 6.02 may be established pursuant to and in accordance with the provisions of this paragraph and may have a first priority Lien on Collateral consisting of Receivables, collections thereof and accounts established solely for the collection of such Receivables, and the Agent is authorized and directed to enter into all such amendments to the Loan Documents as it shall deem necessary or advisable to establish such first priority Lien and to subordinate to such Lien on customary terms (as determined by the Agent and Level 3) the Liens on such

104

Receivables securing the other Obligations. The loans of any class established pursuant to this paragraph shall, to the extent provided in the amendment entered into in connection therewith, be entitled to all the benefits afforded by this Agreement and the other Loan Documents, and shall benefit equally and ratably (except as provided in the next preceding sentence) from the Guarantees created by the Guarantee Agreement and security interests created by the Collateral Agreement and the other Security Documents. Level 3 and the Borrower shall take any actions reasonably required by the Administrative Agent to ensure and/or demonstrate that the Guarantee and Collateral Requirement continues to be satisfied after the establishment of any such revolving credit commitments or class of term loans. Notwithstanding the foregoing of this paragraph (d), no Regulated Grantor Subsidiary shall pledge any assets as collateral in support of any loans of any class established pursuant to this paragraph, nor shall any Regulated Guarantor Subsidiary Guarantee any such loans, unless it has obtained all material (as determined in good faith by the General Counsel of Level 3) authorizations and consents of Federal and State Governmental Authorities required in order for such loans and all other loans outstanding hereunder to be secured by such assets and guaranteed by such Regulated Guarantor Subsidiary.

(e) For each borrowing under an Additional Tranche, the Borrower shall use the net proceeds of each such issuance and additional funds as necessary to lend to Level 3 LLC an amount equal to the principal amount of the Additional Tranche so issued, and the principal amount of the Loan Proceeds Note shall be increased by such amount.

SECTION 9.03. Expenses; Indemnity; Damage Waiver. (a) Level 3 and the Borrower shall pay, on a joint and several basis, (i) all reasonable out-of-pocket expenses incurred by the Agent and its Affiliates, including the reasonable fees, charges and disbursements of counsel for the Agent, in connection with all ministerial activities in the administration of the Loan Documents and any amendments, modifications or waivers of the provisions thereof and (ii) all reasonable out-of-pocket expenses incurred by the Agent and its Affiliates and each Lender in connection with the enforcement of the Loan Documents, including rights under this Section, or in connection with the Loans, but Level 3 and the Borrower shall only be liable for the fees and expenses of counsel for the Agent and one other counsel for all such other Persons (as well as separate local and regulatory counsel). The Borrower also shall pay all Lien search, filing, recording and similar fees incurred by the Collateral Agent in connection with the creation and perfection of the security interests contemplated by the Loan Documents (other than the filing fees in connection with any local fixture filings and the expenses in connection with obtaining real estate descriptions for fixture filings).

(b) Level 3 and the Borrower shall indemnify, on a joint and several basis, the Agent, each Related Party of the Agent (each such Person being called an “ Indemnitee ”) against, and hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities and related expenses, including the fees, charges and disbursements of any counsel for any Indemnitee, incurred by or asserted against any Indemnitee arising out of, in connection with, or as a result of (i) the execution or delivery of any Loan Document or any other agreement or instrument contemplated

105

hereby or thereby, the performance by the parties to the Loan Documents of their respective obligations thereunder or the consummation of the Transactions or any other transactions contemplated hereby or thereby, or the Collateral, (ii) any Loan or the use of the proceeds thereof, (iii) any actual or alleged presence or release of Hazardous Materials on or from any property owned or operated by Level 3, the Borrower or any of the Subsidiaries of Level 3, or any Environmental Liability related in any way to Level 3, the Borrower or any of the Subsidiaries of Level 3, or (iv) any actual or prospective claim, litigation, investigation or proceeding relating to any of the foregoing, whether based on contract, tort or any other theory and regardless of whether any Indemnitee is a party thereto; provided that such indemnity shall not, as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the gross negligence or willful misconduct of such Indemnitee. It is agreed that the expenses for which Level 3 and the Borrower agree to indemnify the Agent under this paragraph shall not include expenses associated with (i) the arrangement and syndication of the Loans, (ii) the preparation, execution and delivery of the Loan Documents, (iii) the enforcement of the Loan Documents or (iv) the filing fees in connection with any local fixture filings and the expenses in connection with obtaining real estate descriptions for fixture filings; provided , that nothing in this sentence shall have the effect of reducing any rights of the Agent or its Affiliates pursuant to paragraph (a) of this Section or of reducing the Borrower’s responsibility for expenses related to claims, litigation, investigations or proceedings referred to in clause (iv) of the immediately preceding sentence.

(c) To the extent that Level 3 and the Borrower fail to pay any amount required to be paid by them to the Agent or any Related Party of the Agent under paragraph (a) or (b) of this Section, each Lender severally agrees to pay to the Agent such Lender’s pro rata share (determined as of the time that the applicable unreimbursed expense or indemnity payment is sought), based on the amount of its Commitment or outstanding Loans or, if no Loans shall be outstanding, on the amount of its Loans on the most recent date on which Loans were outstanding, of such unpaid amount; provided that (i) the unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against the Agent in its capacity as such and (ii) such indemnity shall not, as to the Agent or any Related Party, be available to the extent that such losses, claims, damages, liabilities or related expenses are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the gross negligence or willful misconduct of the Agent or such Related Party, as the case may be.

(d) To the extent permitted by applicable law, neither Level 3 nor the Borrower shall assert, and each hereby waives, any claim against any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of this Agreement or any agreement or instrument contemplated hereby, the Transactions, any Loan or the use of the proceeds thereof.

106

(e) All amounts due under this Section shall be payable promptly after written demand therefor.

SECTION 9.04. Successors and Assigns. (a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto, the Indemnitees and their respective successors and assigns permitted hereby, except that (i) the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of each Lender (and any attempted assignment or transfer by the Borrower without such consent shall be null and void) and (ii) no Lender may assign or otherwise transfer its rights or obligations hereunder except in accordance with this Section. Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, Indemnitees, their respective successors and assigns permitted hereby and, to the extent expressly contemplated hereby, the Related Parties of the Agent) any legal or equitable right, remedy or claim under or by reason of this Agreement.

(b) Any Lender may assign to one or more assignees all or a portion of its rights under this Agreement (including all or a portion of the Loans at the time owing to it) to an Eligible Transferee; provided , that (i) except in the case of an assignment to a Lender, the amount of the Loans of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent) shall be an integral multiple of $1,000,000 (or the entire remaining amount of the assigning Lender’s Loans, if less than $1,000,000) unless the Administrative Agent shall otherwise consent, provided  that (A) in the event of concurrent assignments to two or more assignees that are Affiliates of one another, or to two or more Approved Funds managed by the same investment advisor or by affiliated investment advisors, all such concurrent assignments shall be aggregated in determining compliance with this subsection and (B) in the event of concurrent assignments to or by two or more assignors that are Affiliates of one another, or to or by two or more Approved Funds managed by the same investment advisor or by affiliated investment advisors, all such concurrent assignments shall be aggregated in determining compliance with this subsection; (ii) each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement; (iii) the parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Assumption, together with a processing and recordation fee of $3,500 (except that in the event of (A) concurrent assignments to two or more assignees that are Affiliates of one another, or to two or more Approved Funds managed by the same investment advisor or by affiliated investment advisors or (B) concurrent assignments by two or more assignees that are Affiliates of one another, or by two or more Approved Funds managed by the same investment advisor or by affiliated investment advisors, only one such fee shall be payable); and (iv) the assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire.

(c) Subject to acceptance and recording thereof pursuant to paragraph (d) of this Section, from and after the effective date specified in each Assignment and Assumption the assignee thereunder shall be a party hereto and, to the extent of the

107

interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Sections 2.09, 2.10, 2.11 and 9.03). Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this Section shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with paragraph (f) of this Section. Each assignment hereunder shall be deemed to be an assignment of the related rights under the Security Documents.

(d) The Administrative Agent shall maintain at one of its offices a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitment of, and principal amount of the Loans owing to, each Lender pursuant to the terms hereof from time to time (the “ Register ”). The entries in the Register shall be conclusive, and the Borrower, the Administrative Agent and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower and any Lender at any reasonable time and from time to time upon reasonable prior notice. Upon its receipt of a duly completed Assignment and Assumption executed by an assigning Lender and an assignee, the assignee’s completed Administrative Questionnaire (unless the assignee shall already be a Lender hereunder) and the processing and recordation fee referred to in paragraph (b) of this Section, the Administrative Agent shall accept such Assignment and Assumption and record the information contained therein in the Register. No assignment shall be effective for purposes of this Agreement unless it has been recorded in the Register as provided in this paragraph.

(e) By executing and delivering an Assignment and Assumption, the assigning Lender thereunder and the assignee thereunder shall be deemed to confirm to and agree with each other and the other parties hereto as follows: (i) such assigning Lender warrants that it is the legal and beneficial owner of the interest being assigned thereby free and clear of any adverse claim and that its Commitment and the outstanding balances of its Loans, in each case without giving effect to assignments thereof that have not become effective, are as set forth in such Assignment and Assumption; (ii) except as set forth in clause (i) above, such assigning Lender makes no representation or warranty and assumes no responsibility with respect to any statements, warranties or representations made in or in connection with this Agreement or any other Loan Document or any other instrument or document furnished pursuant hereto or thereto, or the execution, legality, validity, enforceability, genuineness, sufficiency or value of any of the foregoing, or the financial condition of the Loan Parties or the performance or observance by the Loan Parties of any of their obligations under this Agreement or under any other Loan Document or any other instrument or document furnished pursuant hereto or thereto; (iii) each of the assignee and the assignor represents and warrants that it is

108

legally authorized to enter into such Assignment and Assumption; (iv) such assignee confirms that it has received a copy of this Agreement, together with copies of any amendments or consents entered into prior to the date of such Assignment and Assumption and copies of the most recent financial statements delivered pursuant to Section 5.01 and such other documents and information as it has deemed appropriate to make its own credit analysis and decision to enter into such Assignment and Assumption; (v) such assignee will independently and without reliance upon the Agents, such assigning Lender or any other Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement; (vi) such assignee appoints and authorizes the Agents to take such action as agents on its behalf and to exercise such powers under this Agreement and the other Loan Documents as are delegated to them by the terms hereof and thereof, together with such powers as are reasonably incidental thereto; and (vii) such assignee agrees that it will perform in accordance with their terms all the obligations that by the terms of this Agreement are required to be performed by it as a Lender.

(f) (i) Any Lender may, without the consent of the Borrower, or the Administrative Agent, sell participations to one or more other Persons (each a “ Participant ”) in all or a portion of such Lender’s rights and/or obligations under this Agreement (including all or a portion of its Commitment and the Loans owing to it); provided that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (iii) the Borrower, the Administrative Agent and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver that affects such Participant and that, under Section 9.02(b), would require the consent of each affected Lender. Subject to paragraph (f)(ii) of this Section, the Borrower agrees that each Participant shall be entitled to the benefits of Sections 2.09, 2.10 and 2.11 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 9.08 as though it were a Lender, provided such Participant agrees to be subject to Section 2.12(c) as though it were a Lender.

(ii) A Participant shall not be entitled to receive any greater payment under Section 2.09, 2.10 or 2.11 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant unless the sale of the participation to such Participant is made with the Borrower’s prior written consent, which consent shall specifically refer to this exception. A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 2.11 unless the Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrower, to comply with Section 2.11(e) as though it were a Lender.

109

(g) Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank, and this Section shall not apply to any such pledge or assignment of a security interest; provided that no such pledge or assignment of a security interest shall release a Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

SECTION 9.05. Survival. All covenants, agreements, representations and warranties made by the Loan Parties in the Loan Documents and in the certificates or other instruments delivered in connection with or pursuant to this Agreement or any other Loan Document shall be considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of the Loan Documents and the making of any Loans, regardless of any investigation made by any such other party or on its behalf and notwithstanding that the Administrative Agent or any Lender may have had notice or knowledge of any Default or incorrect representation or warranty at the time any credit is extended hereunder, and shall continue in full force and effect as long as the principal of or any accrued interest on any Loan or any other amount payable under this Agreement is outstanding and unpaid and so long as the Commitments have not expired or terminated. The provisions of Sections 2.09, 2.10, 2.11 and 9.03 and Article VIII shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the repayment of the Loans or the termination of this Agreement or any provision hereof.

SECTION 9.06. Counterparts; Integration; Effectiveness. This Agreement may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. Delivery of an executed signature page to this Agreement by facsimile or electronic transmission shall be effective as delivery of a manually signed counterpart of this Agreement. This Agreement, the other Loan Documents and any separate letter agreements with respect to fees payable to the Administrative Agent constitute the entire contract among the parties relating to the subject matter hereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof. This Agreement shall become effective as provided in Section 4.01.

SECTION 9.07. Severability. Any provision of this Agreement held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and enforceability of the remaining provisions hereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction.

SECTION 9.08. Right of Setoff. If an Event of Default shall have occurred and be continuing and the Loans shall have become due and payable pursuant to Article VII, each Lender and each of its Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all

110

deposits (general or special, time or demand, provisional or final) at any time held and other obligations at any time owing by such Lender or Affiliate to or for the credit or the account of the Borrower against any of and all the obligations of the Borrower now or hereafter existing under this Agreement held by such Lender, irrespective of whether or not such Lender shall have made any demand under this Agreement and although such obligations may be unmatured. The rights of each Lender under this Section are in addition to other rights and remedies (including other rights of setoff) which such Lender may have.

SECTION 9.09. Governing Law; Jurisdiction; Consent to Service of Process. (a) This Agreement shall be construed in accordance with and governed by the law of the State of New York.

(b) Each of Level 3 and the Borrower hereby irrevocably and unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of the Supreme Court of the State of New York sitting in New York County and of the United States District Court of the Southern District of New York, and any appellate court from any thereof, in any action or proceeding arising out of or relating to any Loan Document, or for recognition or enforcement of any judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such New York State or, to the extent permitted by law, in such Federal court. Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Agreement or any other Loan Document shall affect any right that the Administrative Agent or any Lender may otherwise have to bring any action or proceeding relating to this Agreement or any other Loan Document against Level 3, the Borrower or its properties in the courts of any jurisdiction.

(c) Each of Level 3 and the Borrower hereby irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement or any other Loan Document in any court referred to in paragraph (b) of this Section. Each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.

(d) Each party to this Agreement irrevocably consents to service of process in the manner provided for notices in Section 9.01. Nothing in this Agreement or any other Loan Document will affect the right of any party to this Agreement to serve process in any other manner permitted by law.

SECTION 9.10. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT, ANY OTHER LOAN DOCUMENT OR THE

111

TRANSACTIONS CONTEMPLATED HEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

SECTION 9.11. Headings. Article and Section headings and the Table of Contents used herein are for convenience of reference only, are not part of this Agreement and shall not affect the construction of, or be taken into consideration in interpreting, this Agreement.

SECTION 9.12. Confidentiality. The Administrative Agent and each Lender agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its and its Affiliates’ directors, officers, employees and agents, including accountants, legal counsel and other advisors (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential), (b) to the extent requested by any regulatory authority, (c) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, (d) to any other party to this Agreement, (e) in connection with the exercise of any remedies hereunder or any suit, action or proceeding relating to this Agreement or any other Loan Document or the enforcement of rights hereunder or thereunder, (f) subject to an agreement containing provisions substantially the same as those of this Section, to any pledgee referred to in Section 9.04(g) or to any assignee of or Participant in, or any prospective assignee of or Participant in, any of its rights or obligations under this Agreement, (g) with the consent of the Borrower, (h) to the extent such Information (i) becomes publicly available other than as a result of a breach of this Section, (ii) becomes available to the Administrative Agent or any Lender on a nonconfidential basis from a source other than Level 3 or the Borrower, (i) to any direct or indirect contractual counterparty in swap agreements or such contractual counterparty’s professional advisor (so long as such contractual counterparty or professional advisor to such contractual counterparty agrees to be bound by the provisions of this Section or (j) to the National Association of Insurance Commissioners or any similar organization or any nationally recognized rating agency that requires access to information about a Lender’s investment portfolio in connection with ratings issued with respect to such Lender. For the purposes of this Section, “ Information ” means all information received from Level 3 or the Borrower relating to Level 3 or the Borrower or its business (including information obtained through the exercise of a Lender’s rights under Sections 5.01) other than any such information that is available to the Administrative Agent or any Lender on a nonconfidential basis prior to disclosure by Level 3 or the Borrower. Any Person required to maintain the confidentiality of Information as provided in this Section shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information.

SECTION 9.13. Interest Rate Limitation. Notwithstanding anything herein to the contrary, if at any time the interest rate applicable to any Loan, together with all fees, charges and other amounts which are treated as interest on such Loan under applicable law (collectively the “ Charges ”), shall exceed the maximum lawful rate (the “ Maximum Rate ”) which may be contracted for, charged, taken, received or reserved by the Lender holding such Loan in accordance with applicable law, the rate of interest payable in respect of such Loan hereunder, together with all Charges payable in respect thereof, shall be limited to the Maximum Rate and, to the extent lawful, the interest and Charges that would have been payable in respect of such Loan but were not payable as a result of the operation of this Section shall be cumulated and the interest and Charges payable to such Lender in respect of other Loans or periods shall be increased (but not above the Maximum Rate therefor) until such cumulated amount, together with interest thereon at the Federal Funds Effective Rate to the date of repayment, shall have been received by such Lender.

SECTION 9.14. Release of Subsidiary Loan Parties and Collateral. (a) Notwithstanding any contrary provision herein or in any other Loan Document, if Level 3 shall request the release under any Security Document of (i) any of its Subsidiaries (other than the Borrower or Level 3 LLC) or any Collateral to be sold or otherwise disposed of (including through the sale or disposition of any Subsidiary (other than the Borrower or Level 3 LLC) owning any such Subsidiary or Collateral) to a Person other than Level 3 or a Subsidiary of Level 3 in a transaction permitted under the terms of this Agreement (including to the extent permitted by Section 6.07, 6.08 or 6.10), (ii) any Receivables, collections thereof and accounts established solely for the collection of such Receivables to secure the Incurrence of Indebtedness pursuant to a Qualified Receivable Facility as permitted by Section 6.01(b)(ii) or 6.02(b)(ii) or (iii) any Property that is to become subject to any Lien permitted to be Incurred under Section 6.05(ii)(3) or (4), and shall deliver to the Collateral Agent a certificate to the effect that such sale or other disposition and the application of the proceeds thereof will comply with the terms of this Agreement and that no Event of Default shall have occurred and be continuing, the Collateral Agent, if satisfied that the applicable certificate is correct, and if satisfied with any arrangements for the receipt and deposit of proceeds of such transaction to the extent required under Section 6.07(b), shall, unless an Event of Default has occurred and is continuing, execute and deliver all such instruments, releases, financing statements or other agreements, and take all such further actions, as shall be necessary to effectuate the release of such Subsidiary or such Collateral substantially simultaneously with or at any time after the completion of such sale or other disposition; provided that if the Collateral to be sold or otherwise disposed of is sold or otherwise disposed of by a Grantor in a transaction permitted by the Credit Agreement to a Person other than Level 3 or a Subsidiary of Level 3, then such Collateral shall be automatically released from any Lien created by this Agreement or any other Loan Document upon the effectiveness of such sale or disposition. Any such release shall be without recourse to, or representation or warranty by, the Collateral Agent and shall not require the consent of any Lender. The Collateral Agent shall execute and deliver all such releases, termination statements or other instruments, and take all such further actions, as shall be necessary to effectuate or confirm any release of Collateral required by this paragraph.

113

(b) Without limiting the provisions of Section 9.03, Level 3 and the Borrower shall reimburse the Collateral Agent for all reasonable out-of-pocket costs and expenses, including the reasonable fees, charges and disbursements of counsel, incurred by it in connection with any action contemplated by this Section.

(c) No such termination or cessation shall release, reduce or otherwise adversely affect the obligations of any other Loan Party under this Agreement or any other Loan Document, all of which obligations continue to remain in full force and effect.

SECTION 9.15. Senior Debt Status. In the event that Level 3 or any Subsidiary of Level 3 shall at any time issue or have outstanding any Indebtedness that by its terms is subordinated to any other Indebtedness of Level 3 or such Subsidiary, Level 3 shall take or cause such Subsidiary to take all such actions as shall be necessary to cause the Obligations to constitute senior indebtedness (however denominated) in respect of such subordinated Indebtedness and to enable the Lenders to have and exercise any payment blockage or other remedies available or potentially available to holders of senior indebtedness under the terms of such subordinated Indebtedness. Without limiting the foregoing, the Obligations are hereby designated as “senior indebtedness” and, if relevant, as “designated senior indebtedness” in respect of all such subordinated Indebtedness and are further given all such other designations as shall be required under the terms of any such subordinated Indebtedness in order that the Lenders may have and exercise any payment blockage or other remedies available or potentially available to holders of senior indebtedness under the terms of such subordinated indebtedness.

SECTION 9.16. No Fiduciary Relationship. Level 3 and the Borrower, on behalf of themselves and the Subsidiaries, agree that in connection with all aspects of the transactions contemplated hereby and any communications in connection therewith, Level 3, the Borrower, the Subsidiaries and their Affiliates, on the one hand, and the Agent and the Lenders and their Affiliates, on the other hand, will have a business relationship that does not create, by implication or otherwise, any fiduciary duty on the part of the Agent, the Lenders, or their Affiliates, and no such duty will be deemed to have arisen in connection with any such transactions or communications.
